you are shorter than you are in the morning time? did you know that? it's true. scout's honor, it's true. now, have you checked it over the weekend? you have in your back, you have a little sack-- you have all these little bones like these. and as you keep going like this, walking along, boom, boom, boom, through the day... [laughter] at the end of the day, you're a little bit-- ever s those jogger types? they start off, "wow, let's go for a run, gang." and they run, boom, boom, boom. at the end of the day, "oh, boy, that was a good workout." [laughter] they get shorter. hey, it's true. you settle right down. and then at nighttime, you get in your bed, you--whooop... you come right back out again, you're all right, huh? now, i got something for you guys to check. i want you to check this out. tonight, before you hit the sack, i want you to find some part of your house that's just about out of your reach. find someplace where you can reach up and find a place-- like i used to have a room that had beamed ceilings, okay? and at nighttime, i could reach up and i couldn't touch those beams. reach, reach, i couldn't touch them.
